stupid really and something and nothing - but here comes the rant 
Went swimming this afternoon me and ds her 2 dd's and her dsd. Dsd comes down every school holiday for few days/ weeks. Well I try and explain to ds that dd's don't get to see her often so they will have to play together etc and dsd won't give him attention. Dsd is 11 btw.
Turned up swimming and in the loo trip dd2 said to ds you are playing with mummy dd1 and me are playing with dsd. Friend denied having said this but I just said I'm sure you can all play together and reinterated to ds they would not want to play alone with him as dsd there.
No probs swimming happily few scuffles - normal kids stuff and then I spoke to dd1 about her new earings. (only had them pierecd a while firt time changed) While I was admiring them etc dd2 came and practically hoved herself in front of me demanding that I look at hers and I simply said ' I'm talking to dd1 at the mo I'll look in a second' Got the feeling friend didn't like this as she started saying 'cuddles' to dd2 who said no. Shes 5 btw.
DD1 was tearful (normal when dsd down0 but I asked who wanted to go to deep and and dive. DSD, ds and dd1 all said yes and dsd swam off while I waited for younger 2.
Before we got out of their depth dd cried as dsd had gone off I said I'd wait then ds overtook dd1 who cried again. I turned to call ds to wait as I needed them both by my when dd1 swam towards me out of her depth. I looked round and said you OK? she was crying so I told ds to come back and grabbed her and then friend came and took her from me really shittily.
Anyway she said something to me and I said don't to shout at me (I didn't feel I had done anything wrong) but know an anger instinct sets in when your scared.
Anyway she was shitty with me and when I got home sent me a text basically accusing me teaching ds to swim by leaving him struggling and that she didn't want her dd1 to learn that way. 
I text back to say I never taught ds that way and in actual fact she knows that ds was in the baby pool for longer than instuctor felt necessary during lessons as he was scared of being in the big pool so I asked them to hold him back. And explained her dd1 was crying before this.
She has text back to say she felt for dd1 and i've said I understand that as I'd be the same but its the accusations that have upset me.
It'll all blow over but I'm just really upset at the mo.
So what happened with your friend )if u don't mind saying) and how did you solve it?
Feel like I should have an AIBU after that rant
